nitrosmith0815 Posted January 30, 2015 Share Posted January 30, 2015 5efe camshafts and ACIS intake from 5efhe and 88hp exhaust manifold 4efe with exhaust and acis will put around 96hp Quote Link to post Share on other sites
mikey4410 Posted January 30, 2015 Share Posted January 30, 2015 Best way and biggest bang for buck is turboing. Quote Link to post Share on other sites
daniel_g Posted January 30, 2015 Share Posted January 30, 2015 This is taken from a N/a performance thread from a while back.This is a list of all the things I'd done/planned to do to my old n/a before I was laid off and went back to school. The most important thing to gain power is the mapping/ecu section to take advantage of all the modifications, without it you'll be lucky to see 100 because the standard ecu just can't cope N/A Performance List Engine:5EFHE cams (not 5EFE)Lightened pulley setsHead skim for compressionPorted headValve springs (there are some uprated valves springs for 4EFTE that can be used in the 4EFE. Eg: speedvision, cruise)Exhaust:4-2-1 corolla bugeye exhaust manifoldOBX racing 5e manifoldHotshots 4e manifold (rocking horse shit, hens teeth etc)Custom mani back exhaust (or cat-back)HeatwrapFuelling:Corolla bug eye injectors (beige/brown in color)Fuel Pressure Regulator (to help with map)After market Uprated Ignition leadsSpark plugs NGK heat range 6 or 7)Could go coilpacks if going nuts but probably not needed)Inlet:Corolla bug eye inlet (tubular manifold)4efte inlet manifold4efte Throttle BodyCooling:Civic alloy dual/triple core radiator (personal preference on core)Air filter (apexi is tried and tested, but whatever you can afford)Low temp thermostatDrive train: Lightened flywheels (various after market ones available)If you go for an off the shelf flywheel, you may need to buy the equivalent FTE clutch kit because the n/a lightened flywheels are really hard to come byCorolla G6r 6 speed gearbox (requires shifter unit and cable mount brackets, possibly the actual selector cables) i may be wrong but its do-ableLightened and balanced crank (if your going all out why not. should get the clutch and flywheel balanced at the same time as the crank)LSD (they are available for the n/a 5 speed but rare. same as the 6speed. best off buying a glanza box and lsd if you dont go 6speed Management:Best way to go is aftermarket ecu, Emanage, Motec, Megasquirt etc (key modification to get the best out of these mods, if your going this crazy)THEN to control all the gained power (probably only around 30bhp if your lucky)Brakes:Levin Twinpot callipers and corolla d4d discs (unsure if they are the correct discs, but there are enough people on here runnign sets to find out)Celica st205 Twinpots (think they are the same as the levin twinpots)Celica st185 big pot calliper (unsure on discs but will refer back to this when i do)GT/Glanza carriers and disc'sThen there are the bigger aftermarket kits like wms, k-sport willwood etc. (bit overkill but if you like flashy then go for it)Suspension/Chassis:Whiteline adjustable rear anti-roll barFront and rear strut bracesCoilovers (dont go lowering springs if your buying for performance)I found the c-pillar bar helped aswellAnti lift kitUprated front anti-roll barPolybush engine mountsAny other various strengthening barsTyres!The biggest difference maker is weight saving for straightline power. so what ever you dont need, get gone (rear seats, right through to smaller batteries and taking a dump before travelling etc) Handling is also the best sector to be modifying these cars in for track use, if you dont want to be shedding out a shed load of dollar AND MOST OF ALL: keep it serviced and looked after!

AdamB Posted January 30, 2015 Share Posted January 30, 2015 Weld the intake ports smaller. Quote Link to post Share on other sites
FrozenJakalope Posted January 31, 2015 Share Posted January 31, 2015 Re: that list Dan, do you really need different injectors? I thought it was all but impossible to max out the stock one without a turbo. Quote Link to post Share on other sites
5e colin Posted January 31, 2015 Share Posted January 31, 2015 also to ad to that list lightning the crank fit forged rods get everythin balanced and rais the revs to 9k Quote Link to post Share on other sites
daniel_g Posted January 31, 2015 Share Posted January 31, 2015 Re: that list Dan, do you really need different injectors? I thought it was all but impossible to max out the stock one without a turbo.I use pink injectors from the Gen1 FE on my N/a GT build. Along with the rest of the Gen1 stuff. ECU, inlet, TB etc. Quote Link to post Share on other sites
